duplicar_curso · Moodle MCP: Risk & Policy

WHAT IT DOES

What duplicar_curso does on Moodle

AI agents use duplicar_curso to create or update resources in Moodle — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Moodle environment.

WHY IT NEEDS A POLICY

Why duplicar_curso needs a policy

The tool creates a new course by cloning an existing one, which is a reversible data modification operation. While it has broad impact (duplicates course structure, activities, blocks, and filters), it does not delete or overwrite existing data irreversibly, nor does it execute arbitrary code or trigger financial transactions.

From the tool's definition Tool description: 'Clone a course into a new one (backup+restore under the hood)' and 'New course is hidden by default' indicate the tool creates a new course entity with copied content.
